Histological and histochemical changes in the colon mucosa after ureterosigmoidostomy or colonic conduit.
A study was made of 22 patients previously subjected to urinary diversion, 12 with ureterosigmoidostomy and 10 with colon conduit. The histological and histochemical examination of biopsies of intestinal mucosa near to and far from the ureteral orifices showed transformations with considerable inflammatory infiltration, variations in the composition of the acid mucins with a prevalence of sialomucins, lengthening and branching of the glandular crypts, and sometimes dysplasias of the epithelium. These structural modifications are typical of transitional mucosa. Transitional mucosa might reflect an aspecific reaction of the intestinal mucosa or alternatively it might signify a precancerous co…
[Hemostatic effectiveness of TachoSil® patches in radiofrequency assisted minor hepatic resection].
Aim. Intra- and postoperative bleeding represents an extremely serious and frequent complication of hepatic surgery. The aim of this study was to evaluate the effectiveness of TachoSil (R) to improve hemostasis in radiofrequency assisted minor hepatic resection. Methods. Between July 2008 and June 2010, 31 patients underwent radiofrequency assisted minor hepatic resection. At the end of the liver resection a sponge of TachoSil (R) was applied on the liver. Results. The mean intraoperative bleeding from the liver was 56.1 mL (range 0-300 mL). No patients received intra- and postoperative blood transfusion. Surgical drains were removed between the first and the sixth-eight postoperative day. …
